Whole-body posture planning in anticipation of a manual prehension task: Prospective and retrospective effects

This study examined the extent to which the anticipation of a manual action task influences whole-body postural planning and orientation. Our participants walked up to a drawer, opened the drawer, then grasped and moved an object in the drawer to another location in the same drawer. The starting placement of the object within the drawer and the final placement of the object in the drawer were varied across trials in either a blocked design (i.e., in trials where the same start and end location were repeated consecutively) or in a mixed fashion. Of primary interest was the posture adopted at the moment of grasping the drawer handle before pulling it out prior to the object manipulation task. Of secondary interest was whether there were sequential effects such that postures adopted in preceding trials influenced postures in subsequent trials. The results indicated that the spatial properties of the forthcoming object manipulation influenced both the postures adopted by the participants and the degree to which the drawer was opened, suggesting a prospective effect. In addition, the adopted postures were more consistent in blocked trials than in mixed trials, suggesting an additional retrospective effect. Overall, our findings suggest that motor planning occurs at the level of the whole body, and reflects both prospective and retrospective influences.     

Does longer job tenure help or hinder job performance?

There are two competing theoretical perspectives on how job tenure might affect job performance. Human capital theory suggests that as knowledge and skill increase with greater tenure, job performance will improve as well. In contrast, the literature on job design suggests that as job tenure increases, employees are likely to become more bored and less motivated at work. Consequently, the gains from human capital acquisition might be offset by losses of motivation. To examine these competing perspectives, we conducted meta-analyses on the relationships of job tenure with four types of job performance: core task performance, citizenship behavior, creativity and innovative behavior, and counterproductive work behavior. The results support the second perspective, as both the linear and curvilinear relationships of job tenure with the four types of job performance are weak. Further, the results do not change in strength across type of research design, job industry, age, or gender.     

Realization and the metaphysics of mind1

According to a familiar view in philosophy of mind, mental states or properties are realized by physical states or properties but are not identical to them. This view is often called realization physicalism. But what is realization? I argue that recent approaches to realization, represented by Carl Gillett's ‘dimensioned’ view, fail to acknowledge some textbook cases of realization. I also argue Gillett's account in particular admits realization relations that should not count if realization physicalism is to be distinguished from its competitors in the usual ways. I offer my own account of realization, and argue that it is superior not only in passing the above tests but also in its utility for answering questions about multiple realizability.     

Assessing the role of aggression,empathy, and self‐serving cognitive distortions in trait emotional manipulation

This study extended the examination of the predictors of emotional manipulation. Participants (N = 243) completed measures of trait emotional manipulation, emotional intelligence, social skills, psychopathy, aggression, empathy, and self‐serving cognitive distortions in a cross‐sectional correlational design. For males, higher levels of emotional intelligence, social information processing, indirect aggression, and self‐serving cognitive distortions significantly predicted emotional manipulation. For females, being younger, higher levels of emotional intelligence, indirect aggression, primary psychopathic traits, and lower levels of social awareness significantly predicted emotional manipulation. However for females, emotional intelligence acted as a suppressor. These findings support previous indications that the mechanisms behind emotional manipulation differ as a function of gender. Future research could include ability, rather than trait measures of emotional manipulation, as well as the role of context (such as intimate relationships or workplace environments), thereby allowing additional examination of the nomological network of emotional manipulation.

Implementation of Cognitive Therapy for PTSD in routine clinical care: Effectiveness and moderators of outcome in a consecutive sample

ObjectiveTrauma-focused psychological treatments are recommended as first-line treatments for Posttraumatic Stress Disorder (PTSD), but clinicians may be concerned that the good outcomes observed in randomized controlled trials (RCTs) may not generalize to the wide range of traumas and presentations seen in clinical practice. This study investigated whether Cognitive Therapy for PTSD (CT-PTSD) can be effectively implemented into a UK National Health Service Outpatient Clinic serving a defined ethnically mixed urban catchment area.MethodA consecutive sample of 330 patients with PTSD (age 17–83) following a wide range of traumas were treated by 34 therapists, who received training and supervision in CT-PTSD. Pre and post treatment data (PTSD symptoms, anxiety, depression) were collected for all patients, including dropouts. Hierarchical linear modeling investigated candidate moderators of outcome and therapist effects.ResultsCT-PTSD was well tolerated and led to very large improvement in PTSD symptoms, depression and anxiety. The majority of patients showed reliable improvement/clinically significant change: intent-to-treat: 78.8%/57.3%; completer: 84.5%/65.1%. Dropouts and unreliable attenders had worse outcome. Statistically reliable symptom exacerbation with treatment was observed in only 1.2% of patients. Treatment gains were maintained during follow-up (M = 280 days, n = 220). Few of the selection criteria used in some RCTs, demographic, diagnostic and trauma characteristics moderated treatment outcome, and only social problems and needing treatment for multiple traumas showed unique moderation effects. There were no random effects of therapist on symptom improvement, but therapists who were inexperienced in CT-PTSD had more dropouts than those with greater experience.ConclusionsThe results support the effectiveness of CT-PTSD and suggest that trauma-focused cognitive behavior therapy can be successfully implemented in routine clinical services treating patients with a wide range of traumas.     

Treating PTSD in refugees and asylum seekers within the general health care system. A randomized controlled multicenter study

Objective

There has been uncertainty about whether refugees and asylum seekers with PTSD can be treated effectively in standard psychiatric settings in industrialized countries. In this study, Narrative Exposure Therapy (NET) was compared to Treatment As Usual (TAU) in 11 general psychiatric health care units in Norway. The focus was on changes in symptom severity and in the diagnostic status for PTSD and depression.

Method

Refugees and asylum seekers fulfilling the DSM-IV criteria for PTSD (N = 81) were randomized with an a-priori probability of 2:1 to either NET (N = 51) or TAU (N = 30). The patients were assessed with Clinician Administered PTSD Scale, Hamilton rating scale for depression and the MINI Neuropsychiatric Interview before treatment, and again at one and six months after the completion.

Results

Both NET and TAU gave clinically relevant symptom reduction both in PTSD and in depression. NET gave significantly more symptom reduction compared to TAU as well as significantly more reduction in participants with PTSD diagnoses. No difference in treatment efficacy was found between refugees and asylum seekers.

Conclusions

The study indicated that refugees and asylum seekers can be treated successfully for PTSD and depression in the general psychiatric health care system; NET appeared to be a promising treatment for both groups.

The role of repeated interviewing in children's responses to cross‐examination‐style questioning

The negative effect of cross‐examination‐style questioning on children's accuracy is likely to be due to the complex and credibility‐challenging questions that characterize the interview. Given that cross‐examination occurs after at least one prior interview, however, it is equally possible that repeated interviewing per se impairs children's accuracy, and that the questions asked have little bearing on children's responses. To examine this issue, 5‐ and 6‐year‐old children (n= 82) and 9‐ and 10‐year‐old children (n= 103) took part in a surprise event and were then interviewed using an analogue of direct examination. Either 1 week or 6 months later, half of the children were re‐interviewed with an analogue of cross‐examination designed to challenge their direct examination responses. Remaining children were re‐interviewed with the same questions that were asked during direct examination. Children's accuracy decreased following their second interview, irrespective of age or delay; however, delay particularly impacted younger children's second interview performance. Children's accuracy was most impaired following a cross‐examination‐style interview. Overall, cross‐examination‐style questioning appears to be particularly detrimental to obtaining accurate event reports from children.
